Abstract: A method of fabricating a concrete slab system places bed of a first concrete on a base. The bed has a top surface, a bottom surface, and edge surfaces. The bed is exposed to a drying environment such that the top surface develops shrinkage cracks and portions of the bed separate from the base. A force applied to the top surface induces non-shrinkage cracks in the bed that extend to the bed's bottom surface. Non-concrete material is placed on the bed's top surface and on each of its edge surfaces. The non-concrete material and bed are covered with a second concrete having stretchable fibers mixed therein.
